Method for producing high-energy high-protein feed by fermenting and decomposing polysaccharide in corn steep liquor

Abstract

The invention relates to a method for producing a high-energy high-protein feed by fermenting and decomposing polysaccharide in corn steep liquor, which comprises the following steps of: respectively carrying out amplification culture on bacillus subtilis, bacillus licheniformis, yeasts and aspergillus oryzae and then adding the obtained product into a seeding tank to cultivate for 60-72 hours to obtain a composite bacterial liquid; mixing and heating the corn steep liquor and water, then adding xylanase, glucanase, protease and fatty acid enzyme into a mixed solution and carrying out heat preservation and fermentation on the mixed solution; adding ammonium sulfate, urea, monopotassium phosphate, magnesium sulfate and caramel into the fermented mixed solution; after uniformly mixing, regulating the pH value into the range of 5.5-6.5; then adding the composite bacterial liquid into the mixed solution, stirring the mixture, filling oxygen into the mixture and fermenting the mixture; and after the mixture is fermented well, spraying the mixture on bran or bean pulp, drying after uniformly stirring, grinding the dried mixture into powder with granularity of less than 2mm, and packaging to obtain the high-protein feed. In the method, the polysaccharide can be sufficiently decomposed. The method has high speed and high efficiency on the aspect of transformation. After being decomposed, a product contains various beneficial microorganism viable bacteria, digestive enzymes, metabolites and small molecule substances which can be sufficiently adsorbed by animals.

Description

technical field [0001] The invention relates to a feed production method, in particular to a method for fermenting and decomposing polysaccharides in corn steep liquor to produce high-energy, high-protein feed. Background technique [0002] At present, among the raw materials used in feed production, corn steep liquor accounts for a large proportion, and the original method directly sprays corn steep liquor on corn bran to make protein raw materials. The content of polysaccharides in corn syrup is as high as 50%, but most of them cannot be absorbed and utilized by animals without decomposition and transformation, and it is easy to cause diarrhea in animals. Sulfate ions in feed production cannot be degraded, resulting in incomplete digestion; inorganic acids affect the animal body and destroy the normal operation of the digestive system; protein cannot be fully absorbed, and large amounts can easily cause animal dehydration; inorganic salt absorption process, causing The bu...
